Controller Kp (disabled) 0x2010:1 REAL 32 0 1159479296 readwrite

In the case of using predictive controllers for current loop the unit is undefined, and the default value is 2500. Moreover, Increasing this parameter directly amplifies the amplitude of applied voltages, and as a result has an effect similar to Kp in the case of using a PID controller.

Range of this torque controller gain is 0 to 100,000,000.

Field weakening enabled 0x2010:4 UDINT 32

readwrite

In many applications, it is required to extend the velocity range of an electric motor.

This parameter enables or disables “Field Weakening”, a feature that increases the speed range of a PM motor by weakening the magnetic field of the rotor linearly over the speed range.

The user should set 3 parameters:

1. Field Weakening Starting Speed (Subitem 6)

2. Field Weakening Ending Speed (Subitem7)

3. Percentage of Field Weakening (f) (Subitem 5)

Note:

While the field weakening feature is enabled, it is assumed that the Drive is in its normal conditions with no fault.

Field weakening percentage 0x2010:5 UDINT 32 0 100 0 readwrite

Percentage of Field weakening. This field can have an integer value in the range of [0-100], and determines the "RMS" value of phase currents which are (only) generated to weaken the field. For example, if set to 10, then 10% of rated current will be injected in motor phases to weaken the rotor field. WARNING: Based on motor type, values more than 25% can lead to instability of torque control service. While tuning, proceed with "small steps", "limited power supply voltage" and "limited power supply current".
